Specification of Letters Patent.

Patented Dec. 5, 1911.

To all whom it may concern:

Be it known that I, Goonwm BROWN, a

' citizen of the United States of America, and

' the coffee is inclosed in a filter-paper shellv a resident of Yonkers,county of Westchester, and'Sta-te of New York, have invented certain newand useful Improve ments in Cofiee-Cartridges, of which the fol: lowingis a specification.

This invention relates particularly to a specially preparedcoffee-percolating cartridge.

The objectof my invention is to provide a percolating cart-ridge soconstructed that so treated that it will serve as a hermeticall'y sealedpacking case whichxwill not let the essential oils of the coffee escapeand become absorbed by the fibers of the inclos in shell while awaitinguse.

- urther objects are to construct the cartridge so that it will form aneffective seal against the passage of air and the escape of the aroma ofthe coflz'ee.

Further objects are to so construct the cartridge that it will form anefiective sket to seal the mouth of a drtipper, such or ex ample as isset forth in ters Patent No. 785,693 ranted to me March 21, 1905, andalso such orexample as is set forth in my a plication for Letters Patent.of the United tates filed April 9, 1908, Sr.

No. 425,976. v

In the accompanyln sheet of drawings which forms a part of t isapplication, Frgure 1 shows in perspective a ercolatin cartridgeconstructed in accor ance wit my invention, and Fig. 2 is a sectionalview of the same.

The cartridge P is made of proper diameter and thickness to fit in thedri per with which it is intended to be used. t consists ofafilter-paper shell filled with cofiee which has been roasted and'finely pulverized or nited States Let- Application filed March 80, 1911.Serial no. 617,799.

powdered. It is preferably in the form of a. round disk. One sheet ofpaper 1; forms the bottom and sides and has its edges turned over the.top. A second circular sheet g a little smaller in diameter than thecartrid e is pasted to the turned over edge of the rst sheet, therebfully inclosin the cofl'ee. The paper, pre erably before Emming into thecartrid e, has applied to it a non-crystallizable suiistance which, byreason of its non-crystallizable character, will,

dry and harden without cracking and preserve the .pa'per in a perfectlynon-absorbent and impervious condition. For this urpose, I findcommercial glucose well suited.

t is made into a thin solution and applied in any suitable way, as bymeans of a rush, by dipping, or runnin through coated rollers, andcompletely lls the pores of the paper. The treated aper 1s moistenedslightly to. render it pliable during the for-.

non-crystallizable substance, substantially as described.
